Hello,
I'm not familiar with coding, however attached is the man for the writev on the system. Help this can provide some additional information.

Hi Daniel,
Attached are the two kamailio logs, unix_socket_log --- run rtp proxy wth -s unix:/tmp/rtpproxy.sock udp_rtpproxy_log --- run rtp proxy with -s udp:*:7722

I got some debug info using the truss as below, hope it can provide some info why it reports "invalid argument" error.
Any suggestions are greatly appreciated.

The write() and writev() functions may fail if:
